Study Notes

Craniotomy

  • A surgical procedure to expose the brain by opening the skull.
  • The focus of nursing care is before surgery.
  • Risks:
    • Infection
    • Hemorrhage
    • Respiratory compromise
    • Increased ICP
  • Nursing Considerations:
    • Encourage patient and family to ask questions about the procedure.
    • Explain that patient's head will be shaved before surgery.
    • Patient may be transferred to ICU for close monitoring.
    • Provide emotional support.

Cerebral Aneurysm Repair

  • Alternative to surgery:
    • Coils can be inserted percutaneously through the femoral artery to occlude the aneurysm.
  • Purpose:
    • To prevent rupture or rebleeding of cerebral aneurysm.

Traumatic Brain Injury (TBI)

  • Types:
    • Blunt trauma (closed or open): More common
    • Penetrating trauma: A foreign object that penetrates the scalp, skull, meninges, or brain tissue.
  • Blunt Trauma:
    • Sudden acceleration or deceleration injury.
    • Coup: Injury to cranial tissues near the point of impact.
    • Countercoup: Impact on the opposite side of the skull, causing a second impact.

Traumatic Brain Injury (TBI) Diagnostic Tests

  • Head CT Scan/Cranial CT Scan: Shows cranial fractures
